Resistance Measurements
1. Set the Function switch to the " W " position.
2. Turn off power to the circuit under test. External voltage across the
components causes invalid readings.
3. Connect the red test lead to the "VW " jack and the black test lead to the
"COM" jack.
4. Connect the test lead to the point of measurements and read the value from
the display.
Diodes Testing
1. Set the Function switch to "
2. Turn off power to the circuit under test. External voltage across the
components causes invalid readings.
3. To toggle between the continity/diode modes, press Range Switch.
4. Touch probes to the diode. A forward-voltage drop is about 0.6V (typical for
a silicon diode).
5. Reverse probes. If the diode is good, "OL" is displayed. If the diode is
shorted, a value near 0mV will be displayed.
6. If the diode is open, "OL" is displayed in both directions.
7. If the junction is measured in a circuit and a low reading is obtained with both
lead connections, the junction may be shunted by a resistance of less than
1kW . In this case the diode must be disconnected from the circuit for
accurate testing.
